Title: Isn't It Ionic? (Don't Ya Think?)

Lesson Overview

Students will present their topics on bonding to the class for everyone to take notes on, supplemental information will be presented as needed (based on quality of presentation). Students will then begin the bonding inquiry activity where they explore ionic and covalent bonds using physical representations of Lewis dot structures to create bonds between elements.
The needs of all learners will be accommodated and met through the following items:
  1. A list of the days' activities will be posted on the board prior to students arriving in class.
  2. The list of the days' activities will be reviewed orally with the students at the start of class.
  3. Information and instructions are presented orally and in writing.
  4. Students are provided multiple opportunities to work in small groups.
  5. Students will be heterogeneously paired/grouped for all group work.
  6. Multiple activities are planned for the day, allowing students opportunities to move around the room.
  7. Students are allowed to choose roles for group poster presentation, not all required to present orally, or to write on poster, so long as they provide an appropriate contribution (for their capabilities) to their group.

Objectives

  • Students will be able to: correctly identify ionic bonds
    • explain the difference between cation and anion
    • predict correct molecular formula for ionic compound created from a given cation and anion
    • draw appropriate Lewis dot structures for ions
    • draw appropriate Lewis dot structures for ionic compounds
  • Students will be able to: correctly identify covalent bonds
    • list how covalent bonds are different from ionic bonds
    • explain how a double or triple bond is formed.
    • predict which elements will form covalent bonds.

Instruction

Opening

Admit Activity/Self Assessment Handout
Have students do the admit portion of handout only

Does anyone have any questions about the presentations before we begin?

OK, in a moment I'm going to have everyone get into their groups from yesterday. You will have 6 minutes to make sure that your presentation is ready and practice your speaking roles if you wish.

You have 6 minutes to prepare, and then we will begin with the group that covered Ionic Bonding.

Learning Activities

Have groups give presentations. 5 Min each, 30 min total
All other students need to take notes on presentations of other topics.
Any supplemental information that was left out of a topic given by instructor before moving on to next topic.

Take 5 Minutes and Fill out Self Assessments portion of handout for the group work.

As they are filling out assessments, pass out inquiry handouts.

Now we are going to take the information we have just learned and do an inquiry activity about bonding. (3 Min review, 30 Min Activity)
We will use our knowledge of the octet rule, Who can tell me what the octet rule is?
We will also use our knowledge of the Lewis dot structures, Who can tell me what a Lewis dot structure shows?

Review with students what it means to make an observation. Notice what is present, what isn't present. Differences or similarities between two or more things. Differences or similarities between what they see and what they expected to see.

Have students work in groups of 4 with the lab table behind/in front of them. Back row can group up together. Have 1 student from each group collect the supplies (note cards, markers, dots) and have groups begin working on inquiry.

Closing

Who can give me an example of an ionic bond?
Who can give me an example of a covalent bond?
What is a cation?
What is an anion?
And what is unique about cations and anions in terms of the octet rule?
Multiple bonds are what kind of bonds?
